Topical corticosteroids (TCSs) are a major part of the foundation of treatment for a wide variety of eczematous and inflammatory skin disorders in both adults and children. Mid-potency TCSs represent an important category as they are often used to treat eczematous dermatoses, such as atopic dermatitis. The TCS product must effectively release the active ingredient and promote cutaneous penetration so that therapeutic activity can occur. As many topical products eventually become available as generic formulations, it is important to recognize that although the active ingredient and its concentration are the same, the vehicle excipients may differ significantly, occasionally leading to potential differences in irritancy, in allergenicity, in effects on epidermal permeability barrier function, and, possibly, in efficacy. Clocortolone pivalate 0.1% cream is a mid-potency TCS formulated in an emollient formulation that has been shown to be effective and well-tolerated in the management of several corticosteroid-responsive dermatoses. This article outlines the pharmacologic and clinical data achieved with the original brand formulation of clocortolone pivalate 0.1% cream, and discusses the establishment of an authorized generic formulation that is identical in formulation to the original brand.
外用皮质类固醇(TCSs)是成人和儿童多种湿疹性及炎症性皮肤病治疗基础的重要组成部分。中效TCSs是一个重要类别,因为它们常被用于治疗湿疹性皮炎,如特应性皮炎。TCS产品必须有效释放活性成分并促进皮肤渗透,以便产生治疗活性。由于许多外用产品最终会以通用制剂形式上市,重要的是要认识到,尽管活性成分及其浓度相同,但赋形剂可能有显著差异,偶尔会导致刺激性、致敏性、对表皮渗透屏障功能的影响以及可能的疗效方面的潜在差异。0.1% 戊酸氯倍他松乳膏是一种以润肤剂配方制成的中效TCS,已证明在治疗几种皮质类固醇反应性皮肤病方面有效且耐受性良好。本文概述了0.1% 戊酸氯倍他松乳膏原品牌配方所取得的药理学和临床数据,并讨论了与原品牌配方相同的授权通用制剂的建立。
